I was working on a project like this about 6 months ago. I believe I was
told that if I get it working, they'll give me a key range to work on. I
ran out of time to finish my own project.
There should be an archive of emails that includes a lot of discussions
about this in the past, but I bet that someone having authority will
reply and tell you.
